Adjustable from 100-250 horsepower, the complete, race-ready ZEX™ LS Series Perimeter Plate Blackout Nitrous System™ for throttle-by-wire applications provides optimum spray efficiency and fuel distribution with nitrous and fuel outlets placed at 12 injection points around the perimeter of the intake manifold’s inlet. The revolutionary Perimeter Plate is a direct fit for all 90mm and larger, “4-bolt” style OEM and aftermarket throttle body/manifold combinations, as well as the new FAST™ LSX_R™/LSX_RT™ 102mm Intake Manifolds. The system uses a patented electronic TPS switch to activate nitrous at wide open throttle for maximum power and safety. As with all ZEX™ Blackout Nitrous Systems™, this kit comes with black powder-coated bottles, carbon-fiber looking hoses and fittings that look great in any street/strip or all out drag-racing application.

ZEX™ Perimeter Plates utilize three revolutionary ZEX™ patented nitrous technologies: Perimeter Injection™, Cryo-Sync™ and Airflow Enhancement™. 

Perimeter Injection™ Technology:
Unlike traditional nitrous kits, the ZEX™ Perimeter Plate employs multiple injection points to create a perfectly atomized blend of fuel and nitrous. This mixture is then fired directly into the center of the intake plenum, ensuring equal dispersal between cylinders. By optimizing cylinder-to cylinder distribution, ZEX™ Perimeter Injection™ Technology generates maximum power without sacrificing engine safety. 

Cryo-Sync™ Technology:
The ZEX™ Perimeter Plate routes the nitrous through a set of internal passages before spraying it into your engine. During this circulation process, the nitrous temperature drops to -127 degrees below zero! This cryogenic phenomenon effectively turns the plate into an ultra-efficient Cryo-Sync™, cooling your carburetor and intake manifold for additional power.

Airflow Enhancement™ Technology:
The ZEX™ Perimeter Plate has been designed to inject the nitrous at an optimized angle, toward the center of the intake plenum. In addition to ensuring proper cylinder distribution, this ZEX™- developed technology creates a pocket of intense low pressure just below the carburetor while the nitrous is being sprayed. This low-pressure area enhances airflow into your engine, which further improves power gains.
